1 Safety Precautions 1.1. General Guidelines

1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been

overheated or damaged by the short circuit.

2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are

properly installed.

3. After servicing, make the following leakage current checks to prevent the customer from being exposed to

shock hazards.

4. When conducting repairs and servicing, do not attempt to modify the equipment, its parts or its materials.

5. When wiring units (with cables, flexible cables or lead wires) are supplied as repair parts and only one wire or

some of the wires have been broken or disconnected, do not attempt to repair or re-wire the units. Replace the

entire wiring unit instead.

6. When conducting repairs and servicing, do not twist the Faston connectors but plug them straight in or unplug

them straight out.

1.1.1. Leakage Current Cold Check

1. Unplug the AC cord and connect a jumper between

the two prongs on the plug.

2. Measure the resistance value, with an ohmmeter,

between the jumpered AC plug and each exposed

metallic cabinet part on the equipment such as

screwheads, connectors, control shafts, etc. When

the exposed metallic part has a return path to the

chassis, the reading should be 100 Mohm and

over. When the exposed metal does not have a

return path to the chassis, the reading must be

.

1.1.2. Leakage Current Hot Check (See Figure 1.)

1. Plug the AC cord directly into the AC outlet. Do

not use an isolation transformer for this check.

2. Connect a 1.5kohm, 10 watts resistor, in parallel

with 0.15μF capacitors, between each exposed

metallic part on the set and a good earth ground

such as a water pipe, as shown in Figure 1.

3. Use an AC voltmeter, with 1000 ohms/volt or

more sensitivity, to measure the potential

across the resistor.

4. Check each exposed metallic part, and

measure the voltage at each point.

5. Reverse the AC plug in the AC outlet and

repeat each of the above measurements.

6. The potential at any point should not exceed

0.75 volts RMS. A leakage current tester

(Simpson Model 229 or equivalent) may be

used to make the hot checks, leakage current

must not exceed 1/2 milliamp. In case a

measurement is outside of the limits specified,

there is a possibility of a shock hazard, and the

equipment should be repaired and rechecked

before it is returned to the customer.

2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly

are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some

field-effect transistors and semiconductor [chip] components. The following techniques should be used to help

reduce the incidence of component damage caused by electrostatic discharge (ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off

any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially

available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying

power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface

such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as [anti-static (ESD

protected)] can generate electrical charge sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to

install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive

foam, aluminum foil or comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the

protective material to the chassis or circuit assembly into which the device will be installed.

Caution

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise ham less motion

such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate

static electricity (ESD) sufficient to damage an ES device).

2.2. About lead free solder (PbF) Note: Lead is listed as (Pb) in the periodic table of elements.

In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.

The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).

That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available.

This model uses Pb Free solder in it’s manufacture due to environmental conservation issues. For service and repair

work, we’d suggest the use of Pb free solder as well, although Pb solder may be used.

PCBs manufactured using lead free solder will have the PbF within a leaf Symbol PbF stamped on the back of PCB.

Caution

• Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 °F

(30~40 °C) higher. Please use a high temperature soldering iron and set it to 700 ± 20 °F (370 ± 10 °C).

• Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).

If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before

applying Pb solder.If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.

• After applying PbF solder to double layered boards, please check the component side for excess solder which

may flow onto the opposite side. (see figure below)

Suggested Pb free solder

There are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper)

solder. However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used.
